Bleeding Wilwoods??

[W80 YAU]

Wondering if anyone who have Wilwood brakes can help me out.

I've bought a set of Wilwood 4pot Superlites with 309mm discs of my mate.
Fitted them yesterday but kinda stumped on how to bleed them as they look like they have 4 nipples as opposed to the 1 nipple on my old 282 calipers.

Sent my mate a text but he hasnt replied back yet as he's dead busy these days.
Anyone with Wilwoods shed a light for me??
Do i just take 1 nipple off and bleed it or do all 4 in a certain order or whatnot?

Here's a pic of the brakes if that helps.


Thanks Will

I would bleed them like the spoons first.

2 top nipples inner one first then outer. Then check the bottom nipples just to be sure you have all the air out.

The "bottom" nipples don't do anything, they are because the caliper isn't sided, so if you put the drivers caliper on the passenger side the "bottom" nipples would then be the top ones

As IJ has said bleed the top 2 only and work from the inside out.

Another tip is, the pedal will feel spongier than the oem calipers due to the increased piston size and will therefore give a longer pedal feel

As above
Don't loosen the bottom nipples, as you'll just get fluid draining out Air is lighter than brake fluid so will rise to the top of the caliper.

My mate bought these from you Freakyparts.

So just to confirm, bleed the top inner nipple (closest to coilover) then top outer one (closest to you)
Here's a pic of them fitted


Thanks for all the info folks.

Wilwood High-Performance Disc Brakes - Frequently Asked Questions (FAQs)

Q:

How do I bleed a multi-piston Caliper with the four-bleed screws?




A:


After the master cylinder has been bled, begin bleeding the calipers starting with the wheel farthest from the master cylinder, usually the right rear and start with the upper outside nipple, then move to the upper inside nipple (never bleed the lower nipples). Repeat the process with each wheel, moving successively toward the wheel closest to the master cylinder. For best results the upper nipples should be pointing straight up because air migrates to the top of the chamber.

Disk are on the wrong way dude. Just a heads up

What makes you say that?

What makes you say that?

The way the grooves are facing. Fair enough that he'll get better pad wear the way they are just now, but i'd say if you're going to spend that much on brakes, pad wear isn't as important as getting the best braking possible.

Feel free to voice your view on it

The way the grooves face bears no relavence to the way the discs should be fitted.

The discs have integral vanes which govern the direction (as you can see in the first picture)

The internal vane should go with the direction of rotation so the left one in the pic at the top is drivers side, the one on the right is passenger side.

In my experience, I've not found any increase in pad wear fitting grooved discs either way around.

Never even noticed the vanes being directional. In that case, I stand corrected!

Thanks for the info Freakyparts.

I was concerned at first whether discs would need to be certain side but my mate said they were sided... luckily we chosed the right disc for each side for the integral vanes.
